I am having the same gr-video-sdl problem reported in the message below
when running ./configure for gnuradio-3.0.3 on Cygwin:
http://lists.gnu.org/archive/html/discuss-gnuradio/2007-02/msg00067.html
The replies pointed out a problem with alloca.h and Cygwin but I didn’t
understand the proposed solution. Can someone elaborate? There appear
to be links to a patch but I have no idea what to do with it.
A related issue I had is that before I even got to the point above,
there was a problem with the fact that SDL was not installed on my
machine. I went back through the “Installing GNU Radio with Cygwin”
installation instructions and noticed there is no mention of installing
SDL. Is this an oversight? I tried following the SDL installation
instructions on the “Installing GNU Radio with MinGW” page and that got
me to the point of the alloca.h error. If someone has a solution, any
chance correct SDL installation instructions could be added to the
Cygwin page?
One final thing is that I noticed the ./configure command line options
on the GNU Radio MingW installation page included mention of SDL in a
couple of places. Those command line options follow for reference:
–disable-gr-audio-windows
–with-boost-include-dir=/usr/local/include/boost
–with-sdl-exec-prefix=/usr/local
CPPFLAGS=“-I/usr/local/include -I/usr/local/include/SDL”
LDFLAGS=-L/usr/local/lib
Does ./configure in Cygwin need similar SDL-related command line
options?
Thanks,
Rob
